i INKING MECHANISM.

.Patented Apr. 27, 1920.

j Application led November 29, 1916. Serial No. 134,181.

To all whom t may concer/n Y Be it known that I, ERNEST JAMES SMITrI, a subject of the King of England, and a resldent of Chicago, in the county of Cook,

and best ink to the printing press with which it operates-and which shall provide ample space upon the face ofthel fountain roller for thel use of a plurality of inking rollers in connection therewith if desired. Another object of my invention is to provide means for scraping the surface of the fountain roller and removing therefrom the paper dust and other foreign substances which gather thereon, and for preventing such foreign matter from coming in contact with the major portion of the ink in the fountain. Further objects of my invention are to improve the form and arrangement of the parts in such a way as to make the fountain more readily and leasily cleanable as when a-change in color of ink when desired, and to improve mechanisms of this type in sundry details hereinafter pointed out. The preferred means by which I have accomplished my several objects are illustrated in the drawings and are hereinafter specically described. That which I believe to be new and desire to cover by' this application is set forth in the claims. In the drawings: Figure 1 is an end view of the preferred form of my improved inking mechanism as seen from one side of a press;

Fig. 2 is a fragmentary view, being substantially a section takenon line 2-2` of Fig. -1 and Fig. 3 is a detailed view, being substantially a section on line 3 3 of Fig. 2. i

Referring to the several v`igures of the drawings in which corresponding parts are indicated by the same reference characters,-

10 indicates the framework of a press having mounted thereon an ink fountain 11 in which is revolubly mounted a fountain Y Yroller 12. The fountain roller 12 is mounted 15 for carrying the roller 12 upward and to the right as viewed in Fig. 1, out of contact with the ,Scrapers hereinafter described. Inking rollers 16v-17 are mounted upon opposite ends of"levers 18 which are adapted to be rockedby any suitablemechanism (not shown) frreciprocating the rollers 16--17` ."uitable' type mounted in a cross-bar 22 and bearing upon the upper face of the blade 20.

Near the lowermost portion of the fountain roller 12 is provided a second scraper,

blade 23 which is adjustable relative to the roller by means of a plurality of set-screws 24 which are adapted to be turned by any suitable wrench applicable from below the in position by means of a shaft 13 which is j ournaled at each end in eccentrics 14 which are adapted to be turned by means of arms fountain. The scraper 23 is adapted to be tightened against the fountain roller 12 sov as to scrape therefrom the major portion of the dust and dirt which is deposited upon said roller by its contact with the inking rollers 16-17. The scraper 23 also serves,

tosupport the supply of ink in the fountain 11, permitting only a slight leakage between the blade and the roller.

Asis best shown in Fig. 2, the fountain 11 is provided at one end .portion with a well or chamber 25,-which is separated from the portion of the fountain below the blade 23 by means of a screen 26. As willbe readily understood, the ink which leaks past the scraper 23, and the surplus ink which'is scraped from the surface of the roller 12 by such blade 23, together with the dirt and dust which are scraped from such roller, are

vstrained by the screen 26, the screen serving to prevent the foreign matter from4 entering the chamber 25.

Means is provided for transferring the strained ink from thel chamber 25 to the fountain 11 above the scraper 23, such means 4 comprising a pumpy 27 operated by a pumprod 28 which in turn is actuated by an ecthe roller 12 is moved upward and to the.

through a port normally closed by a plug' 34 in the bottom of the chamber 25, the ink in the upper portion of the fountain being free to escape through said chamber when right by the appropriate movement of the arms 15 for rocking the eccentrics 14. When substantially all of the ink is drained from the chamber 25, the fountain can be readily cleaned by operating the fountain supplied with a suitable cleansing agent which will serve to loosen the ink on the various parts,

the action of the pump 27 serving to expedite the cleaning operation.

So far as I am aware, I am the first in the` art to provide for supporting the ink in an overshot inking mechanism adjacent to the fountain roller by means of a scraper which serves to scrape thev dirt from the surface of the roller and to deliver such dirt intoV a suitable receptacle outside of the body of ink in the fountain rather than to deliver the dirt into the main ink supply. It will be understood that I do. not wish to be restricted to the use of the particular form of construction illustrated except as hereinafter specifically claimed, it being understood that various changes may be made in the form of structure employed without departing from the spirit of my invention.

` What I claim as my invention and desire to secure by Letters Patent, is

1. In an inking mechanism, the combina'- tion of an ink fountain, a fountain roller revolubly mounted therein, a pair of Scrapers supported in contact with said roller at two points spaced circumferentially thereof, and means for moving said roller out of contact with said Scrapers.

2. In an inking mechanism, the combination of an ink fountain, a fountain roller revolubly mounted therein, a pair of scrapers supported in contact with said roller at separated points circumferentially of the roller, one of said scrapers being arranged to support a supply of ink, and means for straining theink removed from said roller by the latter scraper.

3. In an inking mechanism, the combination of an ink fountain, a fountain roller revolubly mounted therein, a pair of Scrapers supported in contacz with said roller at separated points circumferentially of the roller, one of said Scrapers being arranged to support a supply of ink, means for straining the` ink removed from said roller by the latter scraper, and means for returning the strained ink to the main body of ink in the fountain.

4. In an inking mechanism, the combination of an ink fountain, a fountain roller revolubly mounted therein, an adjustable scraper in contact with said roller near its lowermost point and adapted to support a supply of ink between said roller and the walls of the fountain, means for rotating said roller so as to move upward past the scraper the portion of the roller with which said scraper is in contact, and a second scraper in contact with said roller above said first-named scraper and above the level of the ink in said fountain.
